Effect of D-Aliophen® against early preneoplastic lesions (aberrant crypt foci, ACF), polyps, and tumors induced in the colon of mice by azoxymethane (AOM) (A). Experimental design. Effect of D-Aliophen® (3–300 mg/kg) on the formation of ACF (B), ACF ≥ 4 (C), polyps (D), and tumors (E) induced in the colon of mice by AOM (10 mg/kg). D-Aliophen® was orally administered five times a week. The measurement of the parameters was performed 13 weeks after the first injection of AOM. Bar graphs represent the mean ± SD. Symbols indicate significance: # p < 0.01 or 0.001 vs. untreated, ** p < 0.01 and *** p < 0.001 vs. AOM (n = 5–10 mice).
